There's 2 ways to look at map mods.
One is to consider the map to be used with the standard game, in which case all that's needed is to provide code for only the things that are being changed. That's the most efficient, and that's the tags I provided
The other is to consider the map as it would be used with every possible mod out there, in which case it would be a good idea to define things that goofy modders might change. Now what might a modder change for the negative lamp post? Probably nothing (which is why I selected that one). But maybe it might be made buildable. So yeah InvisibleInGame=yes would be nice to define, as would TechLevel=-1 or 11, and AIBuildThis=no, and Primary=none
